Is there a way to display the RSS feed from my blog higher up on the front page of rivercruiseadvisor.com? Widgets work well, of course, but the widgets are placed below the fold on the page. I'd like for the current posts to display somewhere above the fold.

I see.. in the next couple updates we'll be adding a 'shortcodes' functionality to the features which will make this easy.
Also we will make it possible to simply widgetize the feature boxes.
For now its not so easy.
If you're up to is you can edit the 'template_fboxes.php' file. Duplicate the markup and use WP code to get what you want.
The site looks great by the way.
